Checked the quick build assembly, occasionally final drilled on missing nutplates. Final drill #19 for the nutplates holes along inboard edge of the inboard wing rib.. Dimipled the aft most screw for #8 screw head.

Machine countersink all the other #8 screw head holes and countersink the AN426 holes for the flush rivets.

Deburring and priming done in the Quickbuild shop look ok.
